United States

Composed from ash and wind on snow (a charcoalotype?), an ephemeral outdoor installation, an annual tradition. This one is about 15' diameter. (Previous ones, 30', here, and here, and some snow graffiti here.)
8 hours + to make; 8 minutes to disappear (it rained shortly after completion). Gone like the year.
Indoor version in the works: ash or graphite on sand, larger in scale and longer lived.
